The 32-year-old Smile star donned a green Tommy Hillfigger jumper and a thick black scarf for the outing on Thursday, completing her outfit with a number of rings.

Sweeping her blonde locks away from her face, she finished her funny-looking smoke and was later seen zooming off in the back of a black cab.

A spokesman for the hitmaker said: “No comment".

In 2015 the star was involved in a drugs scandal when a video was posted on her Snapchat account of what appeared to be a man waving a small bag of white powder around at Notting Hill Carnival.

A man in the video can be seen dancing and holding the suspicious bag and the woman filming the video can be heard shouting: “What have you got in your hand?”

It is not clear who asks the question, or who filmed the video and uploaded it to her account although the singer captioned the video with an emoji of a girl with her arms crossed and the word: “drugs".

CONFESS: She has admitted to taking drugs before

Back in 2009, she said: “I’ve taken drugs. I found them and find them fun and I don’t think I’m a bad person because of it.

“I think as long as you’re not being malicious and you’re not hurting people then you should not be ashamed of what you do.”

She has also said she will not stand in the way of her daughters, Ethel and Marnie, trying substances, saying it would be “hypercritical” of her.
